A 21-year-old Lawrence woman who testified last Friday about serving as a lookout in a December robbery at Walmart faces four new misdemeanor charges related to a Sunday incident in the Lawrence Memorial Hospital emergency department.

Jadin M. Schmutz is accused of biting a Lawrence police officer on the hand and striking two emergency department employees during an incident at 5 a.m. Sunday, said Sgt. Matt Sarna, a police spokesman.

Sarna said the two LMH employees alleged Schmutz struck them while they were trying to treat her. None of the injuries were serious, Sarna said. According to the police report, Schmutz was suspected of being under the influence of alcohol.

According to court records, prosecutors Monday afternoon filed one count of misdemeanor battery of a law enforcement officer, two counts of misdemeanor battery and one count of attempted battery against Schmutz, who was taken to Douglas County Jail Sunday on the new charges.

She was arrested in April as one of four people who face conspiracy to commit robbery charges and are suspected of serving as lookouts in a Dec. 13 robbery at Walmart, 3300 Iowa.

Schmutz testified as a witness at a Friday preliminary hearing for Lonnie Schaefer, who faces several counts in the robbery case. Schmutz had been out of jail on bond before her arrest Sunday on the new charges, and a judge set her bond Monday in the new case at $4,000.
